The municipality has an area of 65 sq. km and 3,100
inhabitants. Coat of arms. Red with a crowned lion holding with
the forepaw two silver keys crossed in saltire. [In fact, the
lion holds only one key and the other one is placed over the
first one.] The coat of arms was prescribed by Decree of the
President of the Council, 15 March 1957. The keys recall St.
Peter, to whom the main church of Bunonconvento is dedicated. The
silver lion is said to recall the arms of Siena. An other theory
relates this lion to the Germanic Emperor Henry VII of Luxembourg
(1274-1313; Emperor, 1312-1313), who died in Buonconvento on 24
August 1313. The coat of arms in, current use by the municipality
does not match the official description found in the Decree.Ivan Sache, 15 September 2002
